I have a Gigabyte GA-MA770-UD3 motherboard and wanted to try out a DWA-556 card. With Windows 7 64 bit, the computer wil reboot upon shutting down with this card installed. Putting back in my DWA-552 fixed it. Why would this card do this and how do I prevent it?

Since Windows 7 is in Beta, do you have a correct drivers for that card? have you tried to install first a Vista and pplug that card and upgrade your Vista to Windows 7?

sounds more like a power issue with the motherboard, our drivers and the 556's handling of th instructions to power down.
weird that it works with the 552.

Yes, very strange. I am going to rule out power aside form a specific voltage wit the pci-e bus. I have a 1 Kw PSU and am not over drawing it.
So here are my thought from scouring the internet:
1) The pci-e bus is utilizing the incorrect voltage for that card causing it to loop the motherboard and make it reboot on a shutdown command
2) The motherboard has a flaw in the BIOS causing the pci-e card to incorrectly send a WOL command to reboot on shutdown
3) Windows 7 is utilizing a flawed driver that incorrectly interperts the wifi card to present a WOL reboot command or startup command during normal shutdown.
What I am able to do is kill power to the PSU and the restore power. I then can power up the system via the "power button" and hold it for the bios setting of 4 seconds to shut off the system.
Reason I am going to rule out the motherboard or power is this:
- The DWA-552 PCI card does not suffer from this issue
The driver for both the 552 and 556 are at the very least the latest vista driver (I do not have the revision number right now)
This only happens when issuing a shutdown command from within windows or pressing the power button when Windows is running.
Things still to do:
Test this in another system running Vista to rule out the card.
I will post my findings.

It was PME event wake up in the bios causing this on this card. Perhaps this needs to e addressed ina firmware or driver update?

Hi,
I can confirm this same issue on Windows x64 bit Vista. I cannot confirm the cause because I don't know how to diagnose it. This is a bug and needs to be addressed ASAP, the Vista drivers are supposed to be stable.
As a side note, can this card damage any of the other Hardware in my PC if its screwing with the PSU? After installing this card I was getting corrupted file errors when running games. I suspected my RAM was at fault so I ran memtest application http://hcidesign.com/memtest/ in Vista and it reported an error in reading/writing the memory. I then proceeded to confirm this RAM error with three other RAM diagnostic tools (Vista Memory Diagnostic tool, Memtest86+, Dell Diagnostic Tool) all of which reported absolutely no errors in the RAM after running each one for several days (note that all 3 of these tools do not run in Vista, and note that I took the wifi card out when I was performing these tests.) I would like some help with this issue, but I do not intend to hijack this thread, but I feel these problems are strongly related.
My system is a Dell XPS 630i. It has a Nforce 650i motherboard with 8GB of RAM.

check in your bios for a power setting for PME. If you see anything with those 3 letters or PME event wake up turn it off. I am not sure if this can be fixed by drivers
PME is power management event so yes pme event is redundant but hey what do you expect form computer engineers ;D
